Fertilizer Concentration Effects: It's Not Just mg/L

Fertilizer response depends on nutrient ratios (N-P-K + micros), species-specific needs, and soil pH. Too little reduces growth; too much burns roots. Optimal concentration varies by crop and growth stage.

Balanced nutrition + correct pH = nutrient availability. This is why hydroponic formulas are crop-specific.
